passive seismic
解釋
非人工震源地震技術-
The idea of passive control is to utilize additional facility within a structure to dissipate or absorb a large portion of the seismic energy, which has been applied to practical engineering extensively since its control devices - dampers are convenient and it does not need large energy supply and the structural system identification. now the main devices which have been developed in the passive control may be grouped into the following types : viscous, visco - elastic, metallic and frictional, and tuned mass damper ( tmd ) and tuned liquid damper ( tld )
被動控制通過附加阻尼裝置耗散或吸收大部分的地震動能量以達到減振的目的，由於其控制裝置簡單，不需要外界能源輸入和系統識別，容易在工程上實現並已得到廣泛的應用；目前被應用於結構被動控制的阻尼器主要有：粘滯型、粘彈型、摩擦型、調諧質量阻尼器（ tmd ）和調諧液體阻尼器（ tld ） 。 -
The comparisons of passive isolation control, passive - off control, passive - on control and fuzzy semi - active control show that the roof mr isolation system is a valid and practical intelligent semi - active control system. the roof mr isolation system is quit valid in suppressing the seismic whipping effect of the top machinery building
本文比較了被動隔震控制、被動-關控制和被動-開控制和模糊半主動控制效果。研究表明：安裝屋蓋mr智能隔震系統有效的抑制了升船機頂部廠房的地震鞭梢效應，是一種有效和實用的智能半主動控制系統。 -
The experimental results on seismic simulator verify that the mr damper in the passive off mode provided the information on the minimum effectiveness of the damper if the external power was cut off, in which the seismic responsesof the tall building and podiun structure were reduced. when the mr damper worked in the six kinds of semi - active logic control methods, the seismic responses of the two building were further reduced compared with those when the mr damper worked in the passive off mode
地震模擬振動臺試驗結果表明： mr阻尼器的passiveoff方式是外部電源被切斷時的最低控制效果，能消除原結構地震反應的鞭梢效應，並使主樓和裙房的地震反應有一定的減少，六種半主動邏輯控制方法的減振效果比passiveoff方式更好，多mr阻尼器控制的效果優于單mr阻尼器。 -
One of these methods, passive control using viscoelastic or viscous dampers, has been applied to more and more projects in the past, because they can reduce the seismic response effectively, economically and rarely need to be repaired after they are installed
其中利用粘彈性和粘滯流體阻尼器對結構進行被動控制的方法，由於其有效性、經濟性和安裝后不再需要維護，而被越來越多的結構設計所採用。 -
